Summarization Fidelity

Summarization Fidelity

Opus: Produces summaries that accurately reflect source material. Naturally distinguishes between main claims and supporting detail. Maintains appropriate level of abstraction.

Haiku: Summaries may:

• Overweight content from the beginning/end of the source (position bias)
• Lose nuance (turn hedged claims into definitive statements)
• Miss the central thesis while including peripheral details
• Add interpretive framing not present in the source

Mitigation: Constrain the summarization process.

Step 1: Identify the single main claim or thesis of the text.
        Write it in one sentence.
Step 2: Identify 3 supporting points. Write each in one sentence.
Step 3: Combine into a coherent paragraph of 60-80 words.

Rules:
- The main claim MUST appear in the first sentence of your summary.
- Do not add interpretation or analysis.
- Do not introduce information not in the source.
- If the source hedges a claim ("may", "suggests", "could"),
  preserve the hedging in your summary.

For longer documents, fight position bias:

Divide the text into thirds (beginning, middle, end).
Extract one key point from each third.
Your summary must include content from all three sections.
